1. General description
Ultra low capacitance double rail-to-rail ElectroStatic Discharge (ESD) protection diode in a small
SOT143B Surface-Mounted Device (SMD) plastic package.
The device is designed to protect two high-speed data lines or high-frequency signal lines from the
damage caused by ESD and other transients.
PRTR5V0U2AX integrates two ultra low capacitance rail-to-rail diodes and one additional ESD
protection diode to ensure signal line protection even if no supply voltage is available.

2. Features and benefits
• ESD protection of two high-speed data lines or high frequency signal lines
• Ultra low input/output to ground capacitance: C(I/O-GND) = 1.8 pF
• ESD protection up to 12 kV
• IEC 61000-4-2, level 4 (ESD)
• Very low clamping voltage due to an integrated additional ESD protection diode
• Very low reverse current
• Small SMD plastic package
• Qualified according to AEC-Q101 and recommended for use in automotive applications

3. Applications
• USB 2.0 ports
• Digital Video Interface (DVI)
• High-Definition Multimedia Interface (HDMI)
• Mobile phones
• Digital cameras
• WAN/LAN systems
• PCs, notebooks, printers and other PC peripherals
